A laboratory experiment was developed to enable students to investigate the use of smart hydrogels for potential application in targeted drug delivery. This is challenging for students to explore practically because of the extremely high risks of handling cross-linking agents such as glutaraldehyde. Genipin is a safe and green alternative that has…

Students should enjoy their laboratory classes and for this purpose a project-based activity is added to a conventional physical chemistry laboratory. Students were given project work instead of conventional experiment and then they had to make progress in the project according to instructions and then carry out experiments related to the project.

Discusses a project in which college students equipped a house with three different types of solar energy collectors and two vertical axis windmills. (MLH)

Describes the structure of an in-depth laboratory project chemical engineering. Provides modeling work to guide experimentation and experimental work on heat transfer analysis. Discusses the experimental results and evaluation of the project. (YP)

Described is a simple demonstration of fermentation. The materials needed, the basic experimental set-up, and various projects are outlined. Included are a diagram of an apparatus for measuring carbon dioxide production and a table showing typical results of the effect of pH on fermentation. (RT)

Describes a synthetic organic laboratory experiment which ensures independence of students but is not excessively demanding of instructor time. Each student is provided with different starting materials to prepare different flavones but use the same general procedure, the "organic synthesis" flavone preparation. Various features of this procedure…

IN THE BIOLOGICAL SCIENCES DEPARTMENT OF SACRAMENTO CITY COLLEGE, EMPHASIS HAS BEEN PLACED ON A TYPE OF INDEPENDENT STUDY INVOLVING SELECTION, DESIGN, PERFORMANCE, AND REPORTING OF AN EXPERIMENT TO EVALUATE AN HYPOTHESIS FORMULATED BY THE STUDENT CONCERNING A TOPIC OF HIS SELECTION. THE FACULTY HAS DEVELOPED A PROJECT SELECTION FORM, WITH…

Presents background information, materials needed, and experimental procedures to study enzymes dependent on pyridine nucleotide coenzymes (NAD/NADH). The experiments, suitable for advanced organic or biochemistry courses, require approximately 10-15 hours to complete. (SK)

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

Describes problems with teaching embryology in the traditional manner. Presents a new approach where students prepare presentations, questions, and discussion topics. During laboratory periods, students conducted their own long-term research projects. (PR)

Describes a project on the application of the laser which aims to stimulate the interest of undergraduate students in applied physics and to demonstrate the interaction between light and ultrasonic waves by building a simple laser communication system. (SK)

Describes a method to detect the presence of microgram quantities of nearly any metal in samples of alloys, minerals, water, and air. This chemical-spot testing technique requires no elaborate equipment and can be done by an amateur. (SK)

This book was written to make it easier for classroom teachers to teach students the skills they need to successfully conduct, analyze, and report an experiment and to carry out independent research; it also presents strategies for holding successful science competitions. Part 1 contains field-tested teaching strategies for developing student…

Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances.
